Overview
Mendi is a consumer-grade neurofeedback headband designed to help users train their cognitive focus and mental stamina. Developed in Sweden, the device utilizes functional Near-Infrared Spectroscopy (fNIRS) to monitor blood flow and oxygenation in the prefrontal cortex, pairing with a mobile app to gamify brain training without ongoing subscription fees.

How It Works
The Mendi headband rests on the forehead and uses fNIRS optical sensors to measure changes in blood flow and oxygen levels in the prefrontal cortex. This data is transmitted via Bluetooth to the Mendi companion app for iOS and Android, which translates the physiological signals into a real-time interactive game. As users successfully increase activity in their prefrontal cortex through concentration or relaxation, the game provides positive visual feedback. This creates a neurofeedback loop intended to strengthen neural pathways associated with focus and executive function over time.

Considerations
- The optical sensors are sensitive to light; sessions should be performed away from direct sunlight or bright lamps.
- Requires consistent, long-term use to potentially see cognitive benefits.
- Not a medical device; cannot replace professional treatment for ADHD or other clinical conditions.
- Users may experience an initial learning curve when figuring out how to consciously activate their prefrontal cortex.
